CVE-2026-67425 is a high-severity credential exposure vulnerability in Flyto2 Core affecting versions prior to 2.26.6. The flaw arises because components such as llm.chat can read provider API credentials from environment variables when explicit caller credentials are absent, then automatically attach those secrets as Bearer tokens in outbound Authorization headers to a caller-controlled custom base_url. Although the product includes SSRF validation intended to block loopback, private-network, and metadata targets, that protection still permits requests to public routable hosts. As a result, an attacker can supply a public endpoint they control and cause Flyto2 Core to forward operator-held credentials to that endpoint. Exposed secrets can include API keys used for external AI or vector services, creating a direct path to credential exfiltration without requiring code execution on the runner itself.
